Introduction
ER-FOG-851 Low Cost Fiber Optic Gyroscope (FOG) is specially designed according to the concept of traditional fiber optic gyroscope and adopts mature fiber optic gyroscope manufacturing technology. Our FOG gyroscopes have the characteristics of small volume, light weight, low power consumption, fast start-up, simple operation, convenient to use, which are widely used in INS, IMU, positioning system, north seeking system and platform stabilization.
Applications
Optical pod/flight control platform
INS/IMU
Platform stabilization device
Positioning system
North finding instrument
High precise measurement/navigation system and servo-system
